還是先貼出該例子存于github上的位置

https://github.com/lemonbar/spring-mvc-freemarker

Sping-Framework 的官方文檔簡單列出了在spring-mvc中如何使用freemarker, 但是相對來說提供的信息和例子太少, 所以在這給出一個詳細(xì)的例子.

注：我是在maven基礎(chǔ)上進(jìn)行的構(gòu)建, 很多解釋已經(jīng)在代碼中加了, 所以盡量貼代碼.

1. 整個文件夾結(jié)構(gòu)

src    main        java            com.lemon.spring.controller                GreetingController        webapp            WEB-INF                ftl                    footer.ftl                    header.ftl                    login.ftl                    welcome.ftl                root-context.xml                web.xmlpom.xml

2. pom.xml內(nèi)容
